Material and Supply Inputs to Construction Industries in the Producer Price Index Program

Due to a processing error, relative importance figures, indexes, and percent changes for the material and supply inputs to construction industries indexes were incorrect from January 2002 through April 2002. Incorrect values appeared both on the BLS website from February 15, 2002 through June 12, 2002 and in the January 2002 through April 2002 editions of the PPI Detailed Report. The table below shows the corrected index values. The corrected data are subject to normal PPI procedures that recalculate and finalize 4-month-ago values. The BLS regrets any inconvenience these errors may have caused data users. For further information, call the Section of Index Analysis and Public Information at (202) 691-7705.

1 Indexes in this table are derived from the primary product indexes in table 5 of the PPI Detailed Report that are weighted using 1992 input/output relationships and 1997 weights. These indexes only include inputs to construction which are produced by the mining and manufacturing sectors of the economy, excluding capital equipment. Since they do not include labor or capital costs, these indexes should not be regarded as comprehensive measures of changes in construction costs. See note on page 190 of the July 1986 issue of Producer Price Indexes.

2 The indexes for January 2002 have been recalculated to incorporate late reports and corrections by respondents. All data are subject to revision 4 months after original publication.
